Unique Identifier : AIDSLINE ICA10/94370020 AB OBJECTIVE: To describe the distribution by sex, age and risk factors of HIV infected people, as well as trends in two risk groups from the Province of Buenos Aires, Argentina (population 13.2 million). METHODS: HIV-1 infection was diagnosed according to the algorithm: peripheral lab EIA or PA--Reference Center for AIDS EIA or PA EIA2-IFA-Wb-LIA. EIA (Abbott, O. Teknika) and WB (Sorin, O. Teknika). RESULTS: From Jan 1989 to Apr 1993, 3002 HIV+ individuals elder than 13 were diagnosed. Distribution of risk groups was: 1702 (56.7%) injection drug users IDU; 694 (23.1%) heterosexual way HET; 249 (8.3%) homosexual contacts HO; 127 (4.2%) receptors of blood or blood products; 282 (9.4%) other factors including unknown ones. Mean age was: IDU 23.8, HET 26.7, HO 30.4. Female proportion was 29.9%. From 1989 to 1993 HIV+ IDU proportion decreased (1989 = 70%, 1990 = 66.3%, 1991 = 56.8%, 1992 = 48%, 1993 = 39.4%), while HIV+ HET increased (1989 = 11.8%, 1990 = 18.9%, 1991 = 26.5%, 1992 = 29.8%, 1993 = 30.7%). Rates from Metropolitan Area were similar than that observed for touristic Atlantic coast, and 10 times greater than rural zones rates. CONCLUSIONS: 1) the greatest HIV+ risk group in the Province is IDU; 2) HIV+ HET is an increasing group due to unprotected sex; 3) It shows how HIV is spreading and ramifying through our society.
